The 9T RSD driver sitting next to the hubs is also included. These same style retro GT hubs were sold back in the 1980s. GT started making these again in 2017.

If you buy just the parts here is the hub Specs needed for determining spoke length with a online spoke length Calculator.
Front Hub in Millimeters
Rear Hub in Millimeters
Get your Rims ERD and use these specs in a spoke length calculator and you will have the spoke length needed. If your spokes are plus or minus 2 millimeters you will be OK as long as all the spokes are the same length.
The ERD on say a Sun Rhynolite rim is 395mm for one example. I typed in the dimensions with the online Spoke calculater with 3 cross lacing pattern and got 186mm for both hubs. This size is pretty common so it makes sense too! The most common mistake people make when building their own wheels is the spoke direction. You can see the mistake at the valve hole when the spokes to flow away from the hole making less room for the tube valve.
